This retrospective study examined the occurrence of congenitally missing permanent teeth and the need for dental treatment in the Regensburg University Medical Centre of Eastern Bavaria. Using a dental administration software tool, a total of 1442 patients who presented for orthodontic treatment between 1994 and 2006 were identified. After exclusion of 89 patients with incomplete records, 1353 ...

Hypohidrotic ectodermal dysplasia (HED) is characterized by severe hypohidrosis, hypoplasia of sweat, sebaceous, submucous, meibomian and mammary glands, hypotrichosis, and oligodontia. In early childhood, HED is a life-threatening disorder based on the risks for hyperthermia and pneumonia. Awareness of the hazards related to this rare genetic disease is most helpful in preventing avoidable cal...

The relationship between maxillary lateral incisor anodontia and the palatal displacement of unerupted maxillary canines cannot be considered as a multiple tooth abnormality with defined genetic etiology in order to be regarded as a "syndrome". Neither were the involved genes identified and located in the human genome, nor was it presumed on which chromosome the responsible gene would be locate...

During the diagnosis procedure several other dental and oral symptoms can be observed. However esthetic and psychological problems require special attention for these patients, considering that they are often associated with low self-esteem and problems of social ac...

Mutations in the EDA gene are responsible for X-linked hypohidrotic ectodermal dysplasia, the most common form of ectodermal dysplasia. Males show a severe form of this disease, while females often manifest mild to moderate symptoms. We identified a missense mutation (c.463C>T) in the EDA gene in a Jordanian family, using direct DNA sequencing. This mutation leads to an amino acid change of arg...
